The use of municipal sludge, as a seed to initiate autotrophic nitrogen removal (ANR) process is challenging because the abundance anaerobic ammonia-oxidizing bacteria (AnAOB) negligible. In this study, high-height-diameter-ratio airlift inner-circulation partition bioreactor (HHAIPBR) was operated for 175 d enrich AnAOB from and performance ANR investigated. start-up period HHAIPBR inoculated with sludge required approximately 69 d. A high performance, mean TNRE 82.1%, obtained 1 month. computational fluid dynamics model used simulate volume fraction particle velocity. simulation results perfectly validated DO distribution characteristics inside reactor, further supporting promotion granulation via height-to-diameter ratio. Nitrosomonas (3.31%) Proteobacteria Candidatus Brocadia (6.56%) Planctomycetota were dominant in HHAIPBR. This study presents viable approach industrial cultivation anammox rapid PNA system.

A microfluidic electrochemical sensor is fabricated for the measurement of chemical oxygen demand (COD) in surface waters, such as lakes and reservoirs. An Au interdigital electrode used a substrate, layer nanoparticles (AuNPs) deposited on working (WE) to form functionalized WE. polydimethylsiloxane (PDMS) device was integrated with AuNPs/Au PDMS-AuNPs/Au sensor. Water samples are transferred into out through peristaltic pump Tygon tubes, online COD detection achieved using an workstation. The linear range 0–400 mg/L, limit 0.12 which much lower than concentration 20 mg/L specified by Chinese national standard. In addition, five real water evaluated, values good agreement that standard method. size only $30\times 10\times 5$ mm, each can be obtained within 3 min, no toxic reagents needed. has convenience integration provides new idea detection.
